What happens if you rev with the clutch in?

Clutches are not designed to ‘pull’ a car into moving, and this extra stress put into the clutch can cause quick wear and burn out. Using rev matching by blipping your throttle while the clutch pedal is pressed down is a way of taking this extra work away from the clutch.

Is high revving bad for clutch?

The noise will quiet once you depress the clutch pedal, so if it sounds as if your engine is revving or louder in neutral, you might have problems with your clutch.

What happens if you accelerate and clutch at the same time?

How important is rev matching?

Why Do You Need To Rev Match? Changing down to a lower gear without properly adjusting your speed can cause excess strain on your engine, clutch and gears. By matching the revs, your car won’t jerk forwards due to engine braking which you may have experienced whilst driving in the past.

The car won’t move if the clutch is pressed, and the engine will race if you step on the gas pedal at the same. That would not be a good move for your engine.

How fast should I release clutch?

For your car, bring the engine up to about 1500 RPM (or 1100ish if you don’t mind taking off slower) and bring the clutch to the engagement point.

What causes rev hang?

That extra fuel causes a rich air-fuel ratio, which is bad for emissions. Since modern cars have electronic throttle bodies, the car’s ECU can delay how much the throttle actually closes, despite your foot being all the way off the throttle. This throttle delay is what causes rev hang.

How do you get rid of rev hang?

Elimination/reduction of the rev hang is possible by modifying software in the ECM. There are various after-market companies offering “tunes”, predominantly for the purpose of improving performance by increasing power.
